The Norwegian University of Science and Technology study found greenhouse gas emissions rose dramatically if coal was used to produce the electricity. Electric car factories also emitted more toxic waste than conventional car factories, their report in the Journal of Industrial Energy said.

"The global warming potential from electric vehicle production is about twice that of conventional vehicles."

In addition, producing batteries and electric motors requires a lot of toxic minerals such as nickel, copper and aluminium. Hence, the acidification impact is much greater than that of conventional car production.

In regions where fossil fuels are the main sources of power, electric cars offer no benefits and may even cause more harm, the report said.

"It is counterproductive to promote electric vehicles in regions where electricity is primarily produced from lignite, coal or even heavy oil combustion."

A horse will on average produce between 15 and 35 pounds of manure per day. Consequently, the streets of nineteenth-century cities were covered by horse manure. This in turn attracted huge numbers of flies, and the dried and ground-up manure was blown everywhere. In New York in 1900, the population of 100,000 horses produced 2.5 million pounds of horse manure per day,

1-Your assuming zero solar, wind, natural gas (both thermal and fuel cell) electricity, that by itself makes your posting misleading2-Cars can be charged using solar power during the day, and using idle capacity 10pm-7am, in both cases, using coal produced electricity might be avoidable3-There zero argument to continue using coal, worst case, nuclear is far cleaner (as baseline power production), while a nuclear power plant might poison some people in case an accident happens, coal power plants poisons peop
